Brief introduction
RB-101StypeCODThe rapid analyzer is developed by our company based on the relevant standard "Rapid Digestion Spectrometric Method"(HJ/T 399-2007)》An economical model developed and manufactured through research and developmentcodQuick analyzer. This instrument has the characteristics of safety, simplicity, speed, accuracy, direct reading of concentration, and microcomputer control technology.
Scope of application:Suitable for chemical oxygen demand in surface water, underground, domestic sewage, and industrial wastewater(COD)The measurement.
2、 Detection principle
RB-101s typeCODRapid analyzer, using a closed digestion tube for closed digestion, in a strong acidic solution, using a specialized oxidant containing a certain amount of potassium dichromate, and under the action of a catalyst165Dissolve the water sample at a constant temperature of ℃ to oxidize the reducing substances in the water, and measure their unreduction at different wavelengthsCr6+And the ones produced by being reducedCr3+The total absorbance or measurement of the reduced productCr3+The absorbance.
